Abstract

In a system for a non-contact transmission of electrical energy to a mobile part, the system has a bore introduced into a floor material, a frame part is accommodated in the bore, a receiving part is situated in the frame part, an electronic circuit is situated in the receiving part, the receiving part is at least partially covered by a cover part in the manner of a housing, in particular on one of its sides, a sheet-metal part is situated between the receiving part and the frame part, and the sheet-metal part touches the receiving part and the sheet-metal part touches the frame part.

First claim

The invention claimed is:

1. A system for a non-contact transmission of electrical energy to a mobile part, comprising:
a frame part adapted to be accommodated in a bore provided in a floor material;
a receiver part arranged in the frame part;
an electronic circuit arranged in the receiving part;
a cover at least partially covering the receiver part; and
sheet-metal part arranged between the receiver part and the frame part and touches the receiver part and the frame part.

2. The system according to claim 1 , wherein the cover at least partially covers at least one side of the receiver part.

3. The system according to claim 1 , wherein the sheet-metal part is made of corrugated sheet metal and is produced from aluminum and/or copper.

4. The system according to claim 1 , wherein the frame part is adapted to be integrally connected to the floor material by a casting compound.

5. The system according to claim 1 , wherein the receiver part is made from plastic.

6. The system according to claim 1 , wherein the sheet-metal part is produced from corrugated sheet and surrounds the receiving part in a circumferential direction.

7. The system according to claim 1 , wherein the electronic circuit includes a power inverter and/or a gyrator.

8. The system according to claim 1 , wherein the electronic circuit includes a power inverter and a gyrator, a connection of the power inverter on an alternating voltage side connected to an input side of the gyrator, and an output-side connection of the gyrator is connected to a primary winding, components of the gyrator being resonantly adapted to a frequency of an alternating voltage supplied at an output of the power inverter on the alternating voltage side.

9. The system according to claim 8 , wherein the components of the gyrator includes a capacitance and/or an inductance.

10. The system according to claim 1 , wherein a primary winding, adapted to be inductively coupled to a secondary winding provided on an underside of the mobile part, is provided in the cover part.

11. The system according to claim 1 , wherein a number of corrugations extending in a circumferential direction is greater than twenty.

12. The system according to claim 1 , wherein the sheet-metal part is produced from aluminum or copper.

13. The system according to claim 1 , wherein the cover part is made from plastic.

14. A system for a non-contact transmission of electrical energy to a mobile part, comprising:
a frame part accommodated in a bore provided in a floor material;
a receiver part arranged in the frame part;
an electronic circuit arranged in the receiving part;
a cover at least partially covering the receiver part; and
sheet-metal part arranged between the receiver part and the frame part and touches the receiver part and the frame part.
